METHOD OF PREVENTING APPLE FRUIT FLESH FROM BROWNING

摘要

PURPOSE:A suspension containing calcium phosphate whose particle sizes are less than 10mum and Ca/P molar ratio is in the range from 0.8 to 1.5 is applied to the flesh of apple fruit to prevent it from browning while it is stored at low temperature. CONSTITUTION:Calcium phosphate such as dicalcium phosphate or tricalcium phosphate whose particle sizes are less than 10mum, preferably less than 1mum and Ca/P molar ratio is 0.8-1.5 is applied to the surface of apple fruit. For example, a caclium phosphate suspension of 0.2-5% concentration is sprayed to the fruits on the tree or bruits are dipped in the suspension of 0.5-20%.
